reduce herbicide use by combined application of cultivator and band spraying in sugar beet
نویسندگان
چکیده
in order to reduce herbicide utilization, a 3-year field experiment was carried out with integration of mechanical and chemical weed control methods; in mechanical method, three types of blades (curred- bed knife, square- turn knife and sweep) were used. chemical control was done with chloridazon (wp 80%) and desmedipham (ec 15.7%) in two spraying sheme: once band sparying with 2 l h-1 & twice band sparying with 1 l h-1 of herbicides with 10 days interval. combinations of chemical and mechanical control treatments were compared with conventional control methods including hand hoeing and overall field spraying with 6 l h-1 of herbicides. the results indicated that the best method of weeds control was the combination of cultivation with square-turn knif and once band spraying with 2 l h-1 of herbicides. generally, our results showed that band spraying and cultivation, can reduce herbicides usage about 66% that is important from economical and environmental point of views.

In the conventional methods of herbicide and fertilizer application, a substantial amount of toxic chemicals is sprayed or broadcast into the furrows, which is later washed away by irrigation water and may contaminate ground water, human and animal environment. If herbicide and fertilizer application could be limited to the most needed parts of the field rather than overall broadcasting, the me...
